## 1.3.1 示例架构

`Furion` `Samples` 示例创建采用多层分层设计，主要设计是 `自动抽象工厂` 和 `DDD 领域驱动设计` 相结合。

`Furion` 示例项目结构如下：

- `Furion.Tests`：测试层
- `Solution Items`：解决方案配置层
- `Furion`：框架核心层
- `Furion.Application`：业务应用层
- `Furion.Core`：核心层（实体，层次，其他核心代码）
- `Furion.Database.Migrations`：架构维护层
- `Furion.EntityFramework.Core`：EF Core 配置层
- `Furion.Web.Core`：Web 核心层
- `Furion.Web.Entry`：Web 入口层/启动层

## 1.3.2 `Furion.Tests` 测试层

`Furion.Tests` 是项目的测试层，目前还未整理完成。

## 1.3.3 `Solution Items` 解决方案配置层

源码结构：

```
Solution Items
└.editorconfig
```

`Solution Items` 是用来配置解决方案中一些全局配置的，如每个文件的顶部版权信息，如：

```cs

相关配置在 `.editorconfig` 最后面一行，如：
